7.30 Errors and Exceptions in Java and Multithreaded Programming

Alternately, we can specify

• public Thread(ThreadGroup group, Runnable target)

• public Thread(ThreadGroup group, String name)

• public Thread(ThreadGroup group, Runnable target, String name)

7.20 Key Points

1. Errors are of three types, viz., syntactical errors, logical errors and bugs. Syntactical errors

can be caught by a compiler. Bugs can be fixed by assert statements and debugging.

2. Exceptions, on the other hand, are unusual conditions that occur at a run time and can lead

to errors that can crash a program. Exceptions can be synchronous exceptions like IOEx-

ception. These can be predicted.

3. Exceptions can be asynchronous exceptions like OutOfMemory exception that can ...
